Apple Computer will hold a special event in San Jose on Oct. 12, the second such event in just over four weeks. The invitation sent out on Tuesday by Apple shows closed theater curtains with the words “One more thing…” written on top. Those familiar with Apple CEO Steve Jobs’ keynote speeches will instantly recognize the use of Jobs’ “One more thing” catchphrase, which is often used to indicate a blockbuster announcement. There was no indication on what would be announced at the event.
